Nickel plating is used mainly on articles made from steel and alloys based on copper, zinc, aluminum, and less frequently magnesium, titanium, tungsten, molybdenum, and their alloys. Methods have been developed for the application of nickel to nonmetallic surfaces, such as ceramics, plastics, Bakelite, porcelain, and glass. Nickel plating is used to protect articles from corrosion (under atmospheric conditions and in solutions of alkalies, salts, and weak organic acids) and to increase the wear resistance of parts, as well as for protective and decorative purposes.
